The Interchange newsletter is prepared irregularly (approximately semiannually) by the staff of the ERIC Processing and Reference Facility in order to communicate matters of interest to users of the ERIC database and of other ERIC products and services. Initially, the focus was on computer-oriented users who were receiving the ERIC magnetic tapes and on problems associated with utilizing the ERIC bibliographic database in machine-readable form. In later years, the focus shifted to ERIC users in general, and the newsletter began to disseminate a broad spectrum of information pertaining to ERIC, including: price changes, microfiche products, ERIC Clearinghouse news, search strategies, manual searching, education-related databases, referral information, national-level educational studies, microcomputer news related or extendable to ERIC, new ERIC data elements, lexicographic news, etc. Current major categories for newsletter announcements are: General User Information; Product News; Computer Searching; and Microcomputers. This package consists of the first 24 issues of Interchange, extending from November 1972 through July 1983 (a period of just over 10 years). (WTB)
